Description

Provide a continuous long-term data set, to assess interannual and interdecadal variability of macrozoobenthic assemblages in the estuary of the Patos Lagoon, Southern Brazil.

Purpose

The general purposes of this data bank are to provide information on abundance and biological composition of macrofauna sampled in the Patos Lagoon estuary.

Sampling Description

Study Extent

The samples were obtained every August (winter) and March (summer) between 1998 and 2018, comprising a 20 year’s temporal series, through a bi-annual sampling strategy. Coordinates: Pombas Island, in the Arraial embyment where the sampling points are located: 32°10'12''S and 31°57'36''S Latitude; 52°15'36''W and 52°0'36''W Longitude

Sampling

The samples were taken with a 10-cm-diameter PVC corer (0.0078 m2) buried 20 cm into the substrate. Benthic macrofauna samples were sieved through 0.3-mm meshes, fixed in formaldehyde (4 %), identified to the lowest taxonomic level (40x stereomicroscopes) and preserved in ethanol (70 %). The abundance data for each point represent the number of organisms for each species collected by the PVC corer.

Quality Control

Samples are collected by tecnical staff, Post-Graduate and trained students. The quality of data is checked monthly before the uploading in the data bank.

Method steps

  1. The samples were taken with a 10-cm-diameter PVC corer (0.0078 m2) buried 20 cm into the substrate. Benthic macrofauna samples were sieved through 0.3-mm meshes, fixed in formaldehyde (4 %), identified to the lowest taxonomic level (40x stereomicroscopes) and preserved in ethanol (70 %). The abundance data for each point represent the number of organisms for each species collected by the PVC corer.
  2. Data on composition and abundance of benthic macrofauna inhabiting the Patos Lagoon estuary have been biannually collected from August 1996 to December 2018. Data have been acquired through a biannual strategy, comprising Winter (August) and Summer (March) samplings. Samples are collected by a PVC corer with 20 cm in diameter and washed with a 300 µm sieve. All collected material is preserved in formaldehyde 4 %, the macrofauna specimens are identified and quantified in Laboratory.

Geographic Coverages

The Patos Lagoon at the southern Brazilian coastal plain (Rio Grande do Sul state) is the largest (10,360 km2) choked lagoon in the world stretching in a NE SW direction from the city of Porto Alegre (30º30’ S) to Rio Grande (32º12’ S). In the southern estuarine region, approximately 10 % of total area, a single and narrow inlet connects this lagoon to the Atlantic Ocean. The major tributary rivers at the northern and central areas of Patos Lagoon, and the São Gonçalo channel at the southern area, are significant freshwater sources from an extensive drainage basin. The hydrodynamics of Patos Lagoon estuary is strongly controlled by the discharge of tributary rivers and the action of predominant meteorological factors like winds, rainfall and evaporation.
